Subject: [PATCH] :bug: Fix exporter renderer URI path construction

Apply consistent path construction across bitmap, PDF, and SVG
renderers in the exporter. Use path join utilities instead of
hardcoding the render.html path, ensuring the path is properly
appended to the public URI base path.

- bitmap.cljs: Use u/ensure-path-slash and u/join for path
- pdf.cljs: Use u/join and ensure-path-slash on base-uri
- svg.cljs: Use u/ensure-path-slash and u/join for path
